Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534866, here are decompositions:
- 47 + 31534819 = 31534866
- 67 + 31534799 = 31534866
- 79 + 31534787 = 31534866
- 109 + 31534757 = 31534866
- 113 + 31534753 = 31534866
- 127 + 31534739 = 31534866
- 137 + 31534729 = 31534866
- 157 + 31534709 = 31534866
Showing the first eight; more decompositions exist.
